Because of the amount of weight that the rails in a rail system must support, rail bolts are made of hardened steel.
A rail bolt is used in railway construction as a means of attaching track rails to the surface on which they are applied. In most cases, when a new rail system is built, the anchors for the rails are made of concrete, as opposed to the wood from which they were traditionally made. To attach the track to the concrete anchors, the track must be anchored to the concrete using a mounting bracket that holds the track track in place. Before the rail can be applied to the mounting bracket, the mounting bracket must be anchored to the concrete. This is done using a special track screw.
Due to the amount of weight that any track of the rail system must support at any given time, the anchor system must be as strong as possible to avoid any possibility of displacement. As a result, most mounting brackets as well as track bolts are made from hardened steel. Steel is treated to prevent it from becoming susceptible to rust. These mounting systems that utilize rail screws are mounted and anchored directly to the rail anchors, regardless of whether the rails are made of concrete, wood, or any other material.
The track bolt itself consists of more than just a threaded bolt. Track bolts are generally three-part fasteners, consisting of a threaded bolt, a boss or nut, and a lock washer. The washer prevents the track bolt from moving or loosening due to intense vibrations caused by a passing train.
The nut is placed on the mounting bracket, over the faucet where the screw will be threaded, while the washer is on top of the terminal. The mounting bracket and the handle have opposing teeth which, when engaged with each other, prevent any slippage in the fastening process. After the lock washer is applied to the top of the terminal, the screw is centered over the terminal and driven into the rail anchor via the tap on the mounting bracket. Once the lock washer engages the bolt, the bolt is prevented from slipping or loosening.
As the belt bolt is secured and secured through the mounting bracket onto the belt anchor, the anchor pin or belt pin that is secured by the mounting bracket is pulled down. It then applies pressure to the bottom flange of the rail. This is the most common method for attaching a railway track to the anchors defined for the rail system.
